Application filed. April 30, 1906. Beriall'No. 314,331.

' To all'whom it may concern:

Be it known that I, LEO Aim, of Albany, 1n the county of Albany and State ofN-ew York, have invented certain-new and usefulv Improvements in Eyeglasses;'and I do here by: declare the followin to be a full, clear,

. and exact description the same,-reference :being had to the accompanying drawings,

forming a part of this specification, and .to-

the-reference-numerals marked thereon.

. My present invention relates toimprove- :ments in 'eyeglasseaand particularly to the typeembodying finger-operated nose guards tions of parts all as will-be hereinafter more ful1yexplained, the novel features being :pointed out in the claims at the end of the specification.

-'-In.-the drawin s: Figure 1 re resents a front elevation o a pair of eyeg asses constructed in accordance with my invention. 'F-ig.'2:is a top plan view on an enlarged scale, of the eyeglasses shown in Fig. 1. Fig. 3 represents a central cross section of the eyeglasses shown in Figs. land 2, as viewed from i guards detached from the mounting, and Fig.

the right. Fig. 4 is a 1perspective view of the bridge with the guari s and lenses detached. Fig. 5'is a perspective view of one of the 6 is a view similar to Fig. 3 showing another embodiment of my invention.

Similar reference numerals in the several figures indicate similar parts.

My present invention provides an improved mounting of the type hereinbefore described wherein the nose-guards or bearing portions are so mounted as to require a mini- -mum space between the proximate ends of ,the lenses so as not to-unduly increase the pupillary distance as is necessary in someof the mountings of this general type, and in which certain parts of the mounting are utilc-ized as a mounting or hearing for the guards and their related parts.

a The mounting shown in Figs. 1'5 inclusive illustrates one embodiment of my invention,

comprising'the lenses 1 and 2 connected by a bridge 3, the latter being preferably subv stantia'lly rigid to maintain the proper relation between the lenses, and having preferably the substantially vertically-extending arms or pivot portions 4 and 5 at each side, iEQI round or other appropriate cross-section to-serve as fulcrums, supports or guides for the guards 6. The latter, for the purposes of the present invention,- may be of any desiredtype having a nose-engaging portion 7 at their rear ends, a finger piece or operating projection 8 at their forward ends, and a suitable bearmg, preferably a recess 9 at a point intermediate of the nose-engag1ng portions and the operating projections, adapted to fit Below the bearing portions of the bridge. the bearing of the guard is preferably provided a shouldcr'or seat ll) and at a spaced distance above it is a projection ll, the latter being preferably formed on a part of the bridge, and on the bearing portion of the bridge between the upper side of the guard and the projection 11 is coiled a spring 12, the latter being preferably a helical spring having one end fixed to the projection 11 and its other end attached to a portion of the nose guard at one side of its bearing. These guard-operating springs .are suitably coiled to cause normally a proximating movement of the nose-engaging portions of the guards, and the convolutions of the spring are preferably closely arranged in order to hold the guard down upon the seat and to prevent tilting of the guard, and in order to limit the movement of the guards when disengaged from the wearers nose, it is preferable to provide a stop 13 on each guard arranged to engage a part of the mounting, and these stops will serve to hold the operating projections in position forconvenient operation.

In Fig. 6 the invention. is shown in connec tion with a mounting embodying separable parts, the lens having an attaching device provided with the usual box 14 and fastening screw 15 for securing the attaching portion of the bridge to the lens. The bridge shown in this embodiment of the invention has a substantially vertically-extending portion at each end adapted to be secured in the box of the attaching device, and is preferably narrow to enable it to receive a nose'gu'ard provided with a hole to fit it and serve as a beara ing for'the guard, the latter being slipped on .over the end of the bridge in case a closed aperture is formed in the guard. The guard in this form preferably rests on the top of the boX ,as a support, and is attached to one end of'aspring 16, the latter being coiled about the. vertical portion of the bridge and resting at its upper side against a shoulder 17 on the bridge and having'its extremity attached to a projection 18 preferably formed on the bridge, the guard-operating" spring fitting closely between the shoulder 17 and the upper side of the guard. to hold the latter seated on top of the box to prevent tilting, and as in the previously described form, the spring is properly coiled to normally cause a proximating movement of the nose-engaging portions of the guards. A mounting oi the kind. just described is particularly advan tageous in cases Where it is necessary or de' sir-able to make up the mountin from se a rate parts to suit each individua and its so has the advantage of enabling the use of the ordinary form of eyeglass mountingin connection With the invention, the only special. part required being a bridge of a partiinilar form.

Eyeglasses oi the ty e' embodying my invention possess uabli'i advantages over the ordinary eyeglasses, as the guards are the, only parts that necessarily movable and these may be conveniently operated by the fingers of the We relatively rigid the lenses that lary distance between the lenses.

Another important advantageis obtained by mounting the guards and their 'parts on the bridge, and preferably at points intermediate its attached ends as a journal bearing or guide, as the number of parts requiredis reduced and the construction simplified, and

l as the construction is very compact and neat in appearance, the mounting will not be con spicuous when in use, and While in the pres ent embodiments of the invention, the guards. are shown as mounted on. relatively ver tically extending portions of the bridge, the invention is not limited in this respect, for

. while it is generally preferable that the guards should operate in a substantially horizontal plane, this is not always essential, as the guards in accordance with myresent invention may be applied to bridges o different forms.

I claim as my invention:
